United States (1, 7-11), 3 and one earlier report (2) also included the sulfur content of  Sulfur content of crude oils is the second most important property of crude oils next to API gravity. Sulfur content is expressed as weight percent of sulfur in oil and typically varies in the range from 0.1 to 5.0%wt. The standard methods that are use to measure the sulfur content are ASTM D129, D1552, and D2622, depending on the sulfur level. Crude oils with more than 0.5%wt sulfur need to be treated extensively during petroleum refining. Using the sulfur content, crude oils can be Sulfur (S), vanadium (V) and nickel (Ni) occur naturally in crude oil, and their concentrations vary depending on the geographical region of the oil deposits. Depending on the region some crude may also contain measurable levels of calcium (Ca) and iron (Fe). High metal content can adversely affect the refining process during cracking, making crude oil with low levels of vanadium and nickel more desirable. Excess levels must therefore be removed before refining. Determination of the heptane insoluble asphaltene content of gas oil, diesel fuel, residual fuel oils, lubricating oil, bitumen, and crude petroleum that has been topped to an oil temperature of 260°C.

A comparison study on adsorption and interaction behaviors of diluted bitumen and conventional crude oil on model mineral surface.

Sulfur species compounds detection in crude oil, natural gas, fuels, refined products and chemicals. Intertek laboratories detect and trace level measure sulfur species in petroleum, petroleum-refined products such as fuels and petrochemicals, natural gas, and polymers. The apparatus and the conditions for the sulfur content determination are laid in the given pre­ scriptions (2—4). The determination of sulfur content by the energy- dispersive X-ray fluorescence analysis (5) was per­ formed by means of the energy-dispersive X-ray fluo­ rescence analyzer LAB-X 3000. Crude oil with low sulfur content is classified as “sweet.” Crude oil with a higher sulfur content is classified as “sour.” Sulfur content is considered an undesirable characteristic for both processing and end-product quality. Therefore, sweet crude is typically more desirable and valuable than sour crude. Density ranges from light to heavy, while sulfur content is characterized as sweet or sour. The crude oils represented in the chart are a selection of some of the crude oils marketed in various parts of the world. There are some crude oils both below and above the API gravity range shown in the chart. This results in a higher-priced gasoline than that made from sweet crude oil. Current environmental regulations in the United States strictly limit the sulfur content in refined fuels such as diesel and gasoline. The majority of the sulfur in crude oil occurs bonded to carbon atoms, with a small amount occurring as elemental sulfur in solution and as hydrogen sulfide gas. Sour oil can be toxic and corrosive, especially when the oil contains higher levels of hydrogen sulfide, which is a

Sulphur content determines the quality of a crude oil. Sulphur is a corrosive material which decreases the purity of a crude oil. Therefore, a crude oil with high sulphur content (sour crude) Sulfur species compounds detection in crude oil, natural gas, fuels, refined products and chemicals.

This results in a higher-priced gasoline than that made from sweet crude oil. Current environmental regulations in the United States strictly limit the sulfur content in refined fuels such as diesel and gasoline. The majority of the sulfur in crude oil occurs bonded to carbon atoms, with a small amount occurring as elemental sulfur in solution and as hydrogen sulfide gas. Sour oil can be toxic and corrosive, especially when the oil contains higher levels of hydrogen sulfide, which is a Sulfur is invariably present in petroleum products, feedstock and crude oil. Several analytical methodologies are available to determine the sulfur content from trace level to percentage level. Analytical techniques being employed for sulfur determination in petroleum products, feedstock and crude oil are briefly described in this review article. An analytical method for the determination of sulfur, as the tin mono-sulfide (SnS) molecule, in crude oil using high-resolution continuum source graphite furnace molecular absorption spectrometry (HR-CS GF MAS) has been developed. The technique compensates for density changes in the oil and minimizes the effects of variations in the C/H ratio of the oil. When used on-line the instrument obtains the sulfur measurement in the high-pressure flow conditions required to pump crude oil, typically 800 psig in pipelines.
